Question 128205
You can add the same quantity to both  sides
of an inequality without violating it
Try simple examples like
{{{2 > 1}}}
Suppose I add 1000 to both sides?
{{{1002 > 1001}}}
It's still just as true as it was before
{{{r - 12 < 7}}}
I'll add 12 to both sides
{{{r < 19}}}
The correct choice is (4)
